Since testing lenses is dependant on multiple components in the system,
we use the `unity-lens-test-tool` which is able to talk to the lenses
and examine results they return.

Currently this is not hooked into the build system, but you can run the tests
by invoking `unity-lens-test-tool --test-server-mode ./tests`

Here are some of the use-cases that are missing tests currently:

1) Make sure it's possible to search for CamelCase apps by searching "case",
   plus this should properly work with accented characters as well.
